Concepts of Frequency Domain Equalization. Edition No. 1
VDM Publishing House, April 2008, Pages: 180
The concepts of frequency domain equalization
represent the most powerful strategies to combat
time dispersion caused by multipath propagation in
broadband wireless communication systems. Performing
equalization in the frequency domain allows for a
computational efficient implementation because the
effort grows significantly lower with the bandwidth
compared to equalization in the time domain.
Two well known frequency domain concepts exist: OFDM
(Orthogonal Frequency Division Multiplexing) and SC/
FDE (Single Carrier Transmission with Frequency
Domain Equalization). While the interest on OFDM was
almost overwhelming, the interest on SC/FDE has been
growing rapidly only recently.
A primary topic of this work is the extension and
alternative formulation of the SC/FDE system as it
is usually understood. Further more the basic
concept is characterised in terms of equalization
strategies, higher order modulation schemes,
synchronization, channel estimation, channel coding
or front-end implementation effort.
Finally an overall comparison of OFDM and SC/FDE is
carried out, characterising advantages and
disadvantages.
